Bob,
You'll need at least one more pin for data... But you shouldn't have too
much trouble chasing down a quad serial DAC in one chip. Try Maxim, Analog
Devices, TI, National, Linear Technology, etc.
>I have a project which is seriously challenging my I/O pin count.
>What is the expense, in pin count, of adding an additional serial
>input device? It seems to me that it would be possibly to use one
>synchronous serial ADC and four sychronous serial DAC's using only
>six pins - one pin shared by all for clock, one pin for each device,
>thus costing only one additional pin per device added. Is this valid?
